Hi i want to know wats are the causes for poor paging success rate.n how I will rectify this prob. n wat is the good remedy for this problem.Please can any body help me in this matter.18th September 2006 at 22:06 #42376PixGuest
A paging message is sent to all cells of a LAC, trying to reach a specific mobile phone (= SIM card).
If the mobile is not in the cell, there is a paging failure. Since the mobile is only in one cell, you have a failure in all the other cells.
If this is how the paging success is counted, then it is normal to have a low success rate for paging… If it is not counted like that, then I don’t know (there is no such indicator in Alcatel systems)19th September 2006 at 17:20 #42377SammiGuest
How to verify that SDCCH congestion is due to LA updates,in Siemens system..plz help me19th September 2006 at 23:59 #42378AscMiguelGuest
Hi viky, if you have low paging success, first check the Paging congestion hour by hour and how the load is shared in the diferents LA, if there are no problems may be your system need a Paging channel redimensioning or new LA partitioning.
Check if the system sends a second paging message and the percentage of success (2nd Paging Success).
Let me know your statistical results in order to find a way to help you to resolve the problem.
What vendor is your system?20th September 2006 at 08:51 #42379yogeshGuest

ATIMASCA 5th counter; SUIMASCA 5th counter20th September 2006 at 14:49 #42381sammiGuest
HI vanderley..thx for ur help but I’m not getting how to access these counters and how to understand the data..can you help me on this21st September 2006 at 10:28 #42382VanderleyGuest
This is the siemens names of the row counters, I dont know what are you using for network monitoring. A is attempt, S is successful if you sum all attempts you could see what is the share of LU attempts, If you sum successes you again see the share of LU successful.
ATIMASCA (1,9): Attempted Immediate Assignment Procedure
This measurement gives the number of times an immediate assignment was requested.
Different counters distinguish between the assignment causes.
Attempted immediate assignments of an SDCCH:
Counter No. Att. Imm. Assignment with Cause Valid for MS Phase
1 Answer to paging 1+2
2 Emergency call 1+2
3 Call Reestablishment 1+2
4 Other services (Orig. call, SMS, SS)
5 Location update,all other cases
6 Other procedures (IMSI detach, SMS, SS, etc.) 222nd September 2006 at 14:10 #42383SammiGuest
Hi Vanderley..I appreciate ur help man. we use RCommander for network monitoring.What do u use?22nd September 2006 at 14:50 #42384AdrianGuest
Can anyone tell me why SDCCH has got to be on timeslot 1 and what affect it would have if it is put on anything above timeslot 1. Thanks.22nd September 2006 at 18:02 #42385yogesh_rfGuest
In my Opinion SDCCH is normally put on time slot no.2,and its not a compulsion that you have to put BCCH in slot 1 and SDCCH in timeslot2,But in my opinion it is taken as standard to follow to avoid ambiguity.25th September 2006 at 08:56 #42386VanderleyGuest
Usually the first timeslot is zero.
We extract the row counters into our selfcreated SQL based database for postprocessing. then we create our own queries depending on what we want to see. Let’s say that this is not network monitoring but KPI monitoring.25th September 2006 at 14:34 #42387sammiGuest
HI vanderley..thanks! we have one SQL database for KPI monitoring.But when I want to see the raw data to check the reason for dropped calls, I dont understand anything from that raw data man. Since we r working on the page, i will keep u bugging man..Thx once again26th September 2006 at 09:51 #42388VanderleyGuest
I am using MS access and MapInfo to access the SQL database. Also we created a lot of views in the SQL for different purposes.
If you need help you’re welcome
